Given Input Data is 570, 685, 615, 999

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 685 is 5 x 137

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 999 is 3 x 3 x 3 x 37

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(570, 685) = 78090

GCD(570, 685) = ( 570 x 685 ) / 78090

GCD(570, 685) = 390450 / 78090

GCD(570, 685) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 615

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 615) = 615

GCD(5, 615) = ( 5 x 615 ) / 615

GCD(5, 615) = 3075 / 615

GCD(5, 615) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 999

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 999) = 4995

GCD(5, 999) = ( 5 x 999 ) / 4995

GCD(5, 999) = 4995 / 4995

GCD(5, 999) = 1

GCD of 570, 685, 615, 999 is 1
